Prunus tree named ‘Final 131’

ABSTRACT

‘Final 131’ is a new cultivar of Prunus avium having a medium-strong tree habit, self-fertile flowers, S-alleles S3S4, heart-shaped fruit with a black-red color, a fruit ripening time that is later its male parent ‘Sweetheart’, and fruit that is bigger in size than ‘Sweetheart’.

Latin name of the genus and species: The Latin name of the novel plant variety disclosed herein is Prunus avium L.

Variety denomination: The inventive Prunus avium tree disclosed herein has been given the varietal denomination ‘Final 131’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Prunus avium cultivar hereinafter referred to by the cultivar name ‘Final 131’. This new Prunus cultivar was developed through a breeding program in Baden Wuerttemberg, Germany with the goal of producing good quality fruit with a late ripening time. ‘Final 131’ was selected from a population of seedlings grown from a controlled cross of Prunus avium ‘Spate von Wedler’ (unpatented, female parent) x Prunus avium ‘Sweetheart’ (unpatented, male parent). The first asexual propagation of ‘Final 131’ was carried out in 2006 by hardwood cuttings in Germany and has been asexually reproduced repeatedly by hardwood cuttings since then. ‘Final 131’ has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the unique combination of characteristics of this new cultivar when grown under standard horticultural practices in Germany.

-   -   ‘Final 131’ has less cracking of the fruit than ‘Sweetheart’.     -   ‘Final 131’ has a later fruit ripening time than ‘Sweetheart’.     -   ‘Final 131’ has S-alleles S3S4 and self-fertile flowers.     -   ‘Final 131’ has fruit which are black-red in color and bigger in         size than ‘Sweetheart’.     -   ‘Final 131’ has a medium strong tree habit.

COMPARISON OF ‘FINAL 131’ WITH COMMERCIAL CULTIVARS AND PARENTAL PLANTS

‘Final 131’ is similar to its male parent, ‘Sweetheart’, in that both have S-alleles S3S4, are self-fertile and have a medium strong tree habit. ‘Final 131’ is distinct from ‘Sweetheart’ by its longer stem length, larger fruit size, and a fruit ripening time that is ten days later. In addition, the fruit color of ‘Final 131’ is black-red compared to the more brown black color of the fruit of ‘Sweetheart’.

‘Final 131’ is distinct from the Prunus cultivar ‘Tieton’ (U.S. Pat. No. 11,385), by its S-alleles, which are S3S9 compared to S-alleles S3S4 in ‘Final 131’. ‘Final 131’ is 20 days later in fruit ripening than ‘Regina’ (not patented). The fruit shape of ‘Final 131’ is heart-shaped compared to ‘Regina’, which has a more round-shaped fruit. ‘Final 131’ has firmer fruits than ‘Regina’. Flowering in ‘Final 131’ is medium-early in flowering compared to ‘Regina’, which is very late. 

What is claimed is:
 1. A new and distinct Prunus tree named ‘Final 131’ substantially as illustrated and described herein.
